Cheap, non-approved oil that meets 507 spec - Logic & facts

To add some additional colour to the findings above, I contact Opie Oils for their opinion yesterday and just received their reply: All oils that meet 507 spec are good oils, so just pick whichever brand you have an affinity with, they said.

Not satisfied with this, I've asked for more any detail they have on the differences across different brands (along the lines of "surely some manufacturers only just meet the spec, others exceed it and are their products are better quality?") - also that I want a recommendation with the strongest detergent package now that the Millers EE Nanodrive 5w/30 that’s in there currently has been discontinued and will be dropped in a few month's time to help clean my dirty engine and check for swarf - Their response:

Hi

Yes, you can use any of the ones listed. With the 505.01 and 507.00 oils, there isn't a huge difference with oils that meet the same specs, but to me the EE is a good option (I use it in my car). There are slight differences with the basestocks and additives in the oils that meet the same specs, but not huge differences.

There is a new version of the EE coming out soon, it's due with us any day.

I would use the Comma flush if you want to clean the engine out. Unlike most flushes, it is just detergents, acidity regulators anti-oxidants etc mixed with oil, so is not harmful, like a lot of flushes. It will gently, but thoroughly clean the engine and if any is left behind in the sump, it helps the additive package in the new oil.

So now we're into the other can-of-worms subject here - use of engine oil flushes! That's one for another thread, but suffice to say I respect Opie Oils' opinion above any other retailer.

The link you've shared may not be correct as the oil is over 50 quid even with 15% off? Could you check, or has Brexit pushed the price up?

I wish I’d ordered a few now ...
 
I bought 20 litres of the 507 spec Quantum longlife 5w30 a couple of weeks ago, which is the same stuff Audi would use if you took the car into them for a service.

A friend of mine who is a top mechanic said to forget the brand and just buy the correct approved spec oil as that's the most important thing and I certainly wouldn't be paying £45 for 5 litres of oil, that's just ridiculous.

TPS have special offers on oil from time to time and when I bought mine I paid a tad over £80 for the 20 litres, (£20 for 5 litres) which at that price is crazy not to use the genuine longlife stuff, even though I change it annually and it might have only done 3,000 miles, it's just something I do, oil and filter every year and all the other serviceable items along with it every other year.

I believe the Quantum oil is now made by Fuchs where as a few years ago it was Castrol but from what I've heard the Fuchs is very highly rated so I'm happy.

From my understanding 507 spec oil superseded the 505 spec so is not only the correct oil to use for the tdi but probably better to use than the previously correct 505 spec oil?

507 is absolutely superior in every way - see post 14 on the previous page.

80 quid for 20l of Quantum sounds like a good deal to me - But the Mannol is cheaper and is identical oil as per Paul’s findings using an analysis machine.

@depronman - please tell us which Mannol oil it was you tested?
 
I forgot to mention the one horrible thing with the Quantum oil is it now comes in a cardboard box as opposed to the conventional plastic pourable container and inside the box the 5 litres of oil is in a plastic bag which you would never be able to direct into your oil filler cap without it going everywhere, and has to emptied into an appropriate container.

Obviously done to reduce pollution which is great but a bit of a pain to use but I'm sure all oil manufacturers will be going the same route if they haven't already
 
Just found another seller knocking this out for £55.64 delivered so I've gone ahead - That's Audrey's next 4 oil changes sorted, which is great as I have a dirty engine that needs gentle flushing out through shorter interval between the next few changes.

I paid £45.89 for the exact same thing on the 15th of Feb. Its disappeared into the A2, Caddy and Q5. Should of got more..
It gets worse, now just over £60, and that's before we introduce new import paperwork on our side.

Still a very good deal. For ref, TPS price to me on a 5L box of 507 LL last week was £22 inclusive.

Out of interest the latest TDi was running (I gather) 5/40 of some PD flavour plus Slick 50. Sounds no different on the 507 tbh which I take as good news indeed as 507 is bound to lift economy.
 
Actually, 507 5w/30 is only slightly thinner than the 505 5w/40 - They only just cross the boundary between one grade to another in terms of kinematic viscosity at 100 degrees.

You won’t really notice a difference in sound or economy I would have thought (although it is marginally better for the latter), it’s just a better oil in terms of wear protection and that’s the key rationale for using it.

Ah yes, but I believe Slick 50 as supplied is pretty gloopy (I've never used it) so my point was a positive one: despite dropping what was visibly a thicker oil / deposit / Slick 50 combo and replacing it with a notably more fluid oil, the engine sounds just as happy. I think that's a big first hand, practical tick in 507's box.

Ah I see what you mean.

Slick 50 I think is one of those additives that divides opinion, I’m in the snake oil camp personally and I’m sure I’ve read a study done on it that it actually blocks oil filters - also I read DuPont sued the manufacturer, as Teflon was never designed to be used in this application and they did not approve of its use for fear of reputational damage.

But that’s enough of the thread swerve!

Yes, I'm the same: snake oil, pure and simple. If it wasn't they would publish meaningful peer reviewd data. Thread swerve ends (well, until the word 'flush comes back again anyway :))
 
For anyone interested in the findings of this thread, there's an even cheaper source of Mannol 7715 in 20l form on eBay - SEE HERE - it's £47.99 for 20 litres, that's just under £12 per oil change - with 0.7 litres left over for topping up on the diesels!

I've updated the link earlier in this thread where I was confirmed with @depronman he had a comparison done with Quantum in a lab on this exact oil and found it to be practically identical in composition.

Yes, I was interested. I've just read this and less than a minute later I've ordered it!

Oop's! Impulsive as ever! :mad: It appears that this is collection only! So there's a problem with that .... I wonder if there might be a member near Bradford who could at least have collected it for me and I could then sort things out later?

That's shifty - when I posted the link it was free postage - And now the price has gone up to £59.99!!!

Oh well.

Well I MAY have been lucky! I've received a notification that the oil HAS been dispatched! I'll keep my fingers crossed! :)

Just noticed this: these boxes are brilliant! Used properly they pour extremely fast if you want, you can wring the bag out and get to the last bit of oil. It'll happy take being filled with the waste oil for the tip. When there the bag goes in general waste and the box in the cardboard bin.

I was horrified when the first one arrived: now love them. All you have to do is use them correctly: tab up, reach in and pull out the neck, clip in place, flap down which locks the neck and after that it's a normal can until you recycle the outer later. Also, if you have a bit of oil left in the bag, that can be squished Into one of the accessory holes in the lower boot area for future use.
